Now That's a VFD!

This is a picture of the VFD that drives the pump motor at Pump Station 4 on the Alaska Oil Pipeline. Pump 4 is located about 140 miles south of Prudhoe Bay and 150 miles North of the Arctic Circle. What are the specs? The VFD drives a 6,600 hp motor and supplies over 4.9 MegaWatts of power. Pretty impressive!

The biggest VFD I saw was in a 4 or 5 door electrical enclosure, ran on 480V 3 phase & powered a 600 hp fan motor for a dust collector at a foundry in Saginaw, MI.
